I tested the history settings on 7.0.10 PE with one library by setting it to 1 day and changing the data each day.
I realised, the expired files will be deleted when performing Seaf-gc, but the expired history entries for this file will not be deleted.
So when I click on an expired history entry (e.g. 3 days old), it opens an empty file and when i want to download this file I get an error (the website could not be displayed).
Can someone replicate this? Many thanks in advance!
